This invent-ion relatesin general to'plumbers torches and more' particularly to `means for cleaning the burner nozzle orifice of a plumbers torch. 'V i 5 One object of the invention is to provide a plumbers torch having a novel and improved means whereby the orilice of the'burner noz-V zlecan be easily and quickly cleaned while the torch is in operation Vor'at'any other mtime. Other objects areto provide in plumbers torches a novel and improved combination of fuel controlvalve and means for cleaning the orilice of the burner nozzle; to provide such a construction wherein the fuel control valve rod is screw-threaded for longitudinal movement substantially coaXially with the orifice of the burner block, and iseither also longitudinally slidable or has a part which is longitudinally slidable and carries a wire to be pushed through the orifice of the burner block to remove foreign particles-such as carbon or dust therefrom; to provide novel and improved means for longitudinally sliding the valve rod or a part carriedthereby Vto actuateV the cleaning wire into and out of the orifice; and to obtain other advantages and results as will be brought out bythe fol- Y lowing description. 30 Referring tothe accompanying drawings, in which corresponding and like Vparts are designed throughout the several views by the same reference characters, I

Figure lis' a side elevation of a plumbers torch of known general 'construction and having embodied` therein a burner nozzle cleaning device constructed in accordance with my invention.

Y Figure 2 is an enlargedl vertical longitudinal sectional view through theburner head of the torch.

i Figure 3is asimilar view of. a modified form lof the invention. y y

Figure 4 is a likeview of still another modification of the invention, and l Figure 5 is a transverse vertical sectional view on the line 5,-5lof Figure 4. Y Specifically describing the illustrated em bodiment of the invention, the torch in general 5 comprises a fuel tank or reservoirAhaving a La', handle B "at one side and a vertically projecting fuel pipe C at its top. .Uponthis fuel pipe is mounted a burner head D whichhasa f passage'E leading from the fuel pipe toa burner'block VF which is providediwith afuel lit outlet orifice G. The orifice of the burner i block is approximatelyv horizontally disposed, and in substantially coaxial relationthereto is a combustion tube H into which the fuel i and flame from the burner block orifice is Tifodirected and combustion completed. j

The inner end of the orifice block F has aV valve seat I with which cooperates ahead K on the end of a -coa'Xial valve rod L which is SCI"WV-threaded at M in the burner head and p projects outwardly through a glardfN with its outer` end'provided with a hand wheel for rotating the rod. Itwill be understood fromv this construction that rotation of the valve rodywillV cause movement of the valve i@ l i head K' intoand out'ofengagement with the L valve 'seat I to control the flow of fuel tothe burner block F. Y Movement of the 'valve rod Y L away from the valve seat is limited by a collar P on 'the valve rod which engages the `end @1% of a cap Q, mountedon the burner head. The

foregoing construction is generally old and no claim tonovelty thereon is made. `f

The valve rod L is preferablyl tubular, or M has a longitudinal opening 1-V therethrough j in which is slidable a push rod Q which has'the inner end, i. eg., the end v-insiderthe burner head,

formed with Va headV 3 in which is mounteda cleaning wire ,4 of a ldiameter to looselyv fit the j orifice G of the burner block. The outer, end

of the push-rod projects coaxially from 'the hand wheel O, and the hand wheel is 'prefer ably recessed at its outer side or formed with a concavity as indicatedat 5, to formin effect n a housing for the outer end of the push-rod pressionspring 7 is interposed `between said linger-pieceand the end ofthe valve-rod L VT955.

to normally influenceV the push-rod outwardly j of :thevvalve-rod. This outward movement is limited by the head 3 on the innerend ofthe push-rod. In' operation of the'device, the valverod 451,60 .i

may be located in any of its several positions between full closed andfull open positions for controlling lthe flowf of fuel through the burn'V .er orifice Gr, as desired. Vhen it is desired to clean the orifice VGr, the operator may push inwardlyuponthe finger-piece G of the pushvrod With his Vthumb as indicated by dotted lines in Figure 2 of the drawings. This causes 15Y f I VFigure 3 of the drawings, where the valvethe cleaning wire 4 to be pushed through the orifice Gr, and by'reciprocating the push-rod Vseveral times,cthe oriiice may be thoroughly cleaned. It will be understood that the clean -Y ing. Wire 4 is removed from the orifice by the spring 7 .y Y

A modication of the invention is shown in rod Risthreade'd in a cylindrical block 8 slidable within a cap 19 on thebu'rner head. The

' v cleaning wire ,11, vwhich inlthis case is directlyconnected to the valve-rod kcoaXially therewith;` The outerendof thevalve rodhas a hand-wheel S, and in spaced krelationto the hand-wheel S, a'y collar :12 is secured on thel valve-rod as by a set screw 13. A bracket arm 14 is mounted on the burner head and an op-y erating levei` 15 is-pivotallymounted intermediate Vits ends at 16in a bifurcationl 110Yat the outer end of the bracket arm .14. One end y.17. of .thele'ver is disposed between the collar -12 andtheinner side of the hand-wheel S, While the other endf18 serves as ahandle.

The lvalve-rod has avalvev-headT to coop-y erate with the valve-seatI atthe'inner end oftheburner block. i Y

,f In operation, the supply of fuel tothe burn Verblock is controlled by rotation of the handwheel S vto move the valve head T toward and from the valveeseat I. The .blockV 8 is held Y' -against'rotation by the .pin l0-in lthe sl'ot 100.

Thenthe valvefrod R is rotated-in.one directionvvith the Ablo'ckj engaging' the end of the i `cap 9, the rod is moved longiti'idinallythrough Y having a burner block formed with a fuel out- ,V

the block, whereby the*valve-headY will be forced against the valve-seat-,I Upon rotationofthe valve-rod inthe oppositedirection, the valve-head will lbe moved away fromt-he valve-seat. To clean the nozzle oriceG, itis merely necessary for theoperator to recipro`V particles. -valve-rodis limited bythe block 8 in *thel cap 9, Whilevalve opening movement `ofthe y valve rod fis limitedby 'the operating lever `15 when'fthe latterV swings sov as toeng'age ytherbase of the bifurcation 14() in the bracket cate the valve-rod T by oscillating the op eratinglever 15,'which causes thecleaning Vwire 1.1 tobe reciprocated inthe orifice open ing Gr'soY as tojclear 'it' ofall the foreign Reciprocating movement of *the* arm 14; in which the lever is mounted. f

y :A furthermodificationof theiinvention is j shown in Figureiof thedrawings, wherethe construction is substantially identical With that shown in Figure 3, the only essential dierence being that thegoperating lever 15 is omitted. Here the valve-rod R is reciprocatedby pushing andv pulling upon the hand- V Wheel S to cause the cleaning wire 11y to move into and out of the orifice G. Valve opening movement of the valve-rod is limited by a col-lar. 19 on the valve-rod which engages the block 8 When the latter isin engagement with the outer end of the cap 9.y Y

While I have shown and described several forms of my invention asembodying certain detailsof construction it should be understood that this is primarily for they purpose of illustrating the principles ofl the invention and that manyr modifications and changes may be kmade inthe Vdetails of construction without departing from the spirit or scope of the invention. 1 e i v Similarly,while I havejshown the invention as embodied in a certain type Aof burner head, other uses'oflthe cleaning device will readily occur tovthose skilled intheart; and

therefore I do'not desire to be limited infthe l construction andv use of my invention'except `as required by the followingclaims when construed in the light of the `prior art. HavingV thus' described my invention, what I claim is: j l v a- 1. The combination with av burner. head having a burner block formed with a fuel out.`

let orifice, and a fuel passage leading to ysaid orifice, of a valve-seat iny said passage coaxial:

with said orifice, a valvef-rod-havin'gaV screwthreaded connection in saidl burner head to movev into and out of engagement with'said valve seat upon rotation vof thevalveerodlin opposite directions to control said passage, a cleaning wireto enter saidlorifice and mounted on the inner endof-said'valve-rod,j*and l means mounting saidVvalve-rod in said burn# y Y er head for reciprocation'independently; of

said screw-threaded connection. for `moving said cleaning wire into and out of said orifice.

2.,*The combination with 1a burnerr head let orifice and a fuel passage leading to saidk Y upon said valve'rod and slidable onsaid burnyer head, means for limiting sliding Aof. said block, means for holdingv said-block against Y rotation, and a cleaning Wire to' enterfsaid orifice and mounted on the inner end of said valve-rod, ywhereby said valve-rod fmay be moved intoandY out of engagement withfsaid valve-seat by rotation ofthe valve-rodin op- Y posite directions to controlsaid passage, v'and said cleaning wire lmay be moved into and out rod through sliding of said block.' j
